6 Claims. (U. 229-54) This invention relates to bags, and more particularly to a handle construction for bags.

The principal feature of the invention is the provision of a bag with a novel handle construction which is inexpensive to manufacture and by means of which a filled bag may be conveniently comfortably carried. The invention is particularly applicable to window bags made of paper and provided with a window of transparent or open-mesh material, such as are widely used for packaging produce for sale in grocery stores, though not limited to such bags. Other features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the structures hereinafter described, and the scope of which will be indicated in the following claims.

in the accompanying drawings, in which several of various possible embodiments of the invention are illustrated,

Fig. l is a front elevation, partly broken away and in section, of a window bag embodying my new handle construction, prior to filling and closing of the bag;

Fig. 2 is an enlarged cross section taken on line 22 0. Fig. 1;

Fig. 3 is a perspective showing the Fig. 1 bag opened for filling;

-ig. 4 is a perspective showing the filled and closed in the position in which it is carried; and, rig. 5 is a perspective illus 'ating certain modifications. Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawir 25, Figs. 1-4 illustrate a window bag It made of paper an. provided with a handle construction of my invention. The bag has a window 3 of transparent material, such as cellophane, in its front wall 5. e back wall of the bag is designated "7. The bag has gusset sides 9 and a pasted bottom closure I11 of the so-cailed self-opening square bottom type. Bags of this general ire are presently known, usually being made of two-ply construction (see Fig. 2), with the window 3 consisting of a patch or" cellophane adhesively secured in position between the plies occupying a window opening formed by registering apertures in the plies of the front wall 5. It will be understood that the bag has a longitudinal seam, but that '1 showing of the seam has been omitted for ion of the drawings.

According to on, the is provided with a flexible member 33 which is narrow relative to the width of the bag adapted to form a handle for the bag extending the full height of the bag on the outside of the bag extending into and being pasted in with the pasted bottom closure 11 as indicated at .15 in Fig. l, and readily detachably secured to the outside of the bag in position extending eightwise of the bag. As herein illustrated, the flexible handle member 13 consists of a strip or" paper folded widthwise to provide a flat multiplethickness strip (see Fig. 2, showing the strip folded twice to be of triple thickness). Detachable securement of the flexible handle member 13 to the bag is effected by spotpasting, i. e., by means of spots 17 of paste at intervals along the length of the member (see Fig. 3). In the case of the gusseted bag herein shown, the flexible handle member 23 is disposed in one of the gussets and, as illustrated in Figs. 1-4, it is spot-pasted to one of the panels of one of the gussets 9 so as to lie flat inside the gusset when the bag is flat.

Window bags such as are shown in Figs. 1-3 may be manufactured in quantity production by a procedure involving the forming of a continuous composite two-ply paper web comprising a first paper web which ultimately becomes the outer ply of the bags and a second paper web which ultimately becomes the inner ply or liner of the bags, the two webs having registering window apertures forming window openings in the composite web spaced at bag length intervals along its length, with patches or" cellophane sandwiched between the webs in position closing the window openings and pasted to the webs. Bags are automatically made in a continuous process from this composite web by means of a conventional bag machine in which the composite web is first formed int 2 ube, the tube is segmented into individual lengths of tub g, each of these having a length required to form a bag of the desired size, and each individual length of tubing is automatically bottomed. 1 contemplate tha the bags will be provided with the flexible by combining a continuous length oers r I hide-forming strip with the above-mentioned composite web by means or" a spot pastor. Then, when the tube is segmented into individual lengths of tubing, each such length of tubing will have a spot-pasted handlei'orrning strip extending its full length, the total length of the str 9 being equal to the length of the tubing and t e strip throughout its length lying flat against the tub- When the bag bottom is formed in the bag machine, the bottom end of the strip will be automatically pasted in with the pasted bottom.

Upon til :13 of the bag and upon closure of the top of the bag, the upper end of the flexible handle memher :13 is caught in the top closure. Fig. 4 illustrate the bag with a stitched top closure 19, and it will be seen how the upper end of member 13 is stitched in the fiattened upper end of the gusset 9 by the closure. Now, to utilize the member as a handle for carrying the bag, the fingers of the hand are inserted under the member, and the length of the member between the bottom and top bag closures separated from the bag by tearing apart the spot-pasted areas 37. it will be seen that the bag lies horizontally when carried by handle member 13. The member 13, being of considerable width, presents a relatively broad handle area to the fingers of the hand so that the bag r be comfortably carried. it will be understood t e handle member 13 will be of sufiicient strength to withstand tearing apart under the load of the filled bag, and tr is end securements in the bottom and top bag closures will also be of sumcient strength to resist tearing out under the load of the filled bag.

Fig. 5 illustrates the application of the above-described princ les to anoth type of paper window bag designated wh: h has an open-mesh window 23 instead of a cellophane v low, and a stitched bottom closure 25 instead of a. pasted bottom closure. The bag 21 is provided with a no :ible mere. er 27 in all respects like member 13 of Figs. 1-4 and spot-pasted to the bag as indicated at 29 in the same manner that member 13 in spot-pasted. The handle member 27 is caught in the bottom closure 25 and becomes caught in the top closure upon closing the bag 21 after it has been filled.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim:

1. A bag comprising a length of tubing having gusset sides and formed at one end with a bag bottom closure, said bottom closure comprising means securing together portions of the tubing at said one end thereof, said bag being provided with a flexible handle member which is narrow relative to the width of the bag and which extends the full length of the tubing on the outside thereof in one of the gussets and which is caught at its lower end by said means in the bottom closure, the total length of the flexible member being equal to the length of the tubing and the flexible member throughout its length lying flat against the tubing, the flexible member being secured to the tubing in the region between the bottom closure and the top of the bag by securing means which fastens the flexible member in position extending heightwise of the bag but which allows for the member to be readily separated from the tubing except at the bottom closure.
